Incat Crowther to design catamaran ferry for Thailand’s Lomprayah

Incat Crowther is to design a 461 passenger 32 m catamaran ferry, to be constructed by the Seacrest Marine shipyard in Thailand. It will be the sixth vessel designed by Incat Crowther for Thai high speed ferry operator Lomprayah, following on from two 29 m catamarans that have been very successful, leading to a growth in Lomprayah’s operation.

The new vessel utilizes Incat Crowther’s plum stem hull form which delivers excellent fuel economy and seakeeping, and gives it a very low cost per passenger mile.

For this project, Incat Crowther has been contracted to deliver a full production design package that improves build efficiency and reduces material wastage. The design package consists of all major structure, including nested and cut aluminum, as well as major fit-out components such as windows and air conditioning. The package also includes three-dimensional systems design, which will detail all piping runs and fittings.

Passengers will board the vessel through bulwark gates on both decks. The main deck, which accommodates 241 passengers, has a large luggage area aft, as well as five toilet spaces. There is a large canteen at the aft end of the main deck cabin, whilst a second luggage area is provided at the forward end of the main cabin.

The upper deck cabin is split between has a mix of economy class seats and VIP seats in a separate rooms. Outdoor seats are provided on the aft upper deck, whilst there are also seats on the roof deck.

A pair of MTU 16V2000 M72 main engines, each producing 1440 kW, will easily push the vessel to a service speed of 25 knots, with propulsion by propellers.
